Z43H Z43X steel plate valve uses:
Plate valve used in natural gas, petroleum, chemical, environmental protection, urban pipeline, gas pipeline and other transportation lines, the venting system and steam storage device, used for hoisting equipment. Z43-type single gate type with diversion holes plate valve used in natural gas extraction and purification of the long pipeline.
Z43H Z43X steel flat gate structure Features:
1. seat sealing structure should have an elastic preload, upstream and downstream sealing seat while sealing structure. The seal between the valve seat and is always face to face seal.
2. The seat has a self-cleaning function, and open or close the process from erosion in direct airflow valve. Seat should be lubricated, do not wear material made.
3. The failure of the valve actuator will not affect other parts of the valve, repair and replacement work can be performed without removing the valve.
(1) yoke casing - aluminum bronze yoke sleeve configuration needle thrust bearings, to minimize operating torque.
(2) stem - Threaded length until the bracket; pin and spot welding; have stability.
(3) sealing pressure - a simple structure, configuration, segmented retaining ring and silver-plated low carbon steel gasket to aid removal and to achieve the best bonnet seal.
(4) seat rings - welded seat ring perpendicular to the flow channel, easy to maintain.
(5) implementing agencies - these valves can be electric, hydraulic or pneumatic actuator. DN300 following configuration standard manual handle, DN350 above configuration helical gear operating mechanism.
(6) Yoke - fully fabricated yoke through seismic testing, ease of maintenance and installation of the actuator.
(7) Gland - two piece, self-adjusting gland to avoid being ejected.
(8) as a whole back seat - hard surface, the longest service life.
(9) the valve - the valve spring load can adjust itself to reduce the torque demand actuator.
(10) Overall stopper - the whole cast bracket stop device, positioning the valve assembly of the bracket, making the seat more stable and reliable.
